JAMES JOHNSON, OF EAST HAMPSTEAD, NEW HAMPSHIRE.

PLOW-COLTER.

SPECIFICATION forming part of Letters Patent No. 299,396, dated May 27,1884.

Application filed April 23, 1883.

To all whom it may concern.-

Be it known that 1, JAMES JoHNsoN, a citizen of the United States,residing at East Hampstead, in the county of Rockingham and State of NewHampshire, have invented a new and useful Improvement in a CombinedGolter and Reversible Mold-Board, of which the following is aspecification.

The object of my invention is to so arrange the eolter as to cause itslower edge to bear against thelandside of the plow-point at everyreversion of the mold-board in a reversible or side-hill plow.

In plow colters as ordinarily applied a space is left between the pointand lower edge of the eolter and the point of the plow suffieient toallow of the passage of roots and other obstructions which clog theplow, and necessitate the stopping of the work to remove theobstructions, and often times causing the breaking of the beam at thecenter-bolt connection.

The invention consists in beveling thelower end of the eolter to an edgeand arranging the front edge of the same so as to bring it as near aspracticable on a line with the land side of the mold-board, thus causingthe opposite side of the plow-point to be presented to an opposite sideof the eolter-point at every reversion of the mold board.

Referring to the accompanying drawings, Figure 1 represents a plowcontaining my improvement. Fig. 2 represents the eolter enlarged. Fig. 3represents the brace, and Fig. 4: is a section of the eolter on the line00 a: of Fig. 2.

A is the plow-beam. Bis a reversible moldboard, of any ordinaryconstruction, and C the plow-point. These parts, being well known,

require no further description.

D is the eolter, which passes through and is The upper bolted to thebeam A, as shown.

(No model.)

edge, d, and lower ends, 6, of the lower portion of the eolter are madeconsiderably sharp, as shown. The lower beveled end, a, of the colter isplaced in contact with the upper side of 5 other device for setting theeolter, as heretofore used, and cause the plow-point to be brought inproper relation to the eolter at every reversion of the mold-boardwithout changing the position of the eolter.

E is a brace bolted to the eolter D, as shown, and attached at its otherend to the under part of the front portion of the beam A, by means ofwhich the eolter is relieved from the strain to which it wouldotherwisebesubjected in coming in contact with roots and otherobstructions.

\Vhat I claim as my invention is- The eolter D, having a sharp edge, d,on the upper part of the lower portion, and a sharpened end, 6, incombination with the beam A and brace E, and the reversible plow-point Cand reversible moldboard 13, whereby the lower end of the eolter is madeto bear against the land side of the plow-point at every reversion ofthe mold-board, as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JAMES JOHNSON.
